WhatsApp High Security Mode Explained: Why Meta Launched Strict Account Settings
Meta has launched WhatsApp’s new High Security Mode amid rising scrutiny over encryption, offering enhanced protections for users facing sophisticated cyber threats, but raising questions about timing and intent.
Here’s an Explainer…
Why did WhatsApp launch High Security Mode?
WhatsApp introduced its new High Security Mode, officially called Strict Account Settings, on January 27, 2026, describing it as a one-click safeguard against rare but highly sophisticated cyberattacks.
The company said the feature is primarily aimed at public figures, journalists, activists, and high-risk users. However, analysts noted that most users are already protected by end-to-end encryption, making the additional layer optional rather than essential for everyday use.
What protections does it provide?
Strict Account Settings activates multiple security controls simultaneously. It blocks media from unknown senders, disables link previews, and silences calls from unfamiliar contacts.
The mode also restricts visibility of last seen and online status, limits who can add users to groups, and enables two-step verification by default. Security code change notifications are automatically turned on, and all calls are routed through WhatsApp servers to mask users’ IP addresses and locations.
How does it compare to Apple and Google’s security features?
WhatsApp becomes the third major tech platform to introduce a high-security mode. Apple launched Lockdown Mode in 2022 for iPhones and Macs, disabling most message attachments and limiting FaceTime calls. Google followed with Advanced Protection Mode for Android, restricting sideloaded apps and tightening account access.
Like its rivals, WhatsApp’s feature prioritises safety over convenience, resulting in a more restrictive user experience.
Where can users enable High Security Mode?
The feature can be found under Settings > Privacy > Advanced on both iOS and Android devices. WhatsApp said the rollout will take place globally over the coming weeks.
Meta cautioned that activating the mode will limit how the app functions, but offers stronger protection for users at elevated risk.
Why is WhatsApp facing renewed security scrutiny?
The launch comes amid growing criticism of WhatsApp’s security claims. A lawsuit filed in San Francisco federal court alleges that Meta can access WhatsApp messages despite assurances of end-to-end encryption.
Tesla and X owner Elon Musk publicly claimed that “WhatsApp is not secure” and urged users to switch to X Chat, while Telegram founder Pavel Durov also questioned WhatsApp’s security posture in 2026.
How did WhatsApp respond to these allegations?
WhatsApp head Will Cathcart firmly rejected the claims, stating that encryption keys are stored on users’ devices, not on Meta’s servers, making it impossible for the company to read messages.
He reiterated that WhatsApp cannot access private conversations and that encryption remains intact.

What other security improvements has WhatsApp made?
Meta has quietly strengthened WhatsApp’s backend security by replacing its older C++ media processing library with Rust, a programming language known for preventing memory-related vulnerabilities.
According to reports, the new system validates media file formats more rigorously, reducing the risk posed by maliciously crafted files.
What recent features has WhatsApp rolled out?
In 2025, WhatsApp introduced Meta AI tools for image generation and message summaries. It also launched a full-featured iPad app and added Apple Watch support.
Looking ahead to 2026, WhatsApp plans to roll out a username-based system under the Omnichat framework, requiring businesses to update systems by June.
What new business capabilities were added?
The WhatsApp Business Platform now supports voice and video calls for large enterprises. Business AI tools have expanded to more markets, offering personalised product recommendations.
Meta’s Ads Manager also allows businesses to manage campaigns across Facebook, Instagram, and WhatsApp from a single dashboard.
